BPA Free Plastic Bin safe?

[BAUCE]

Are these clear plastic bins safe for my frag tank? I bought them to put sand in inside my sump.

It doesn’t actually say what it is made from that I could find, but it is likely fine. I would clean it carefully inside with warm soapy water and rinse very well to remove things like mold release agents that might have been used in manufacturing.

Are there any visible signs I should look out for after putting it in the tank?

Just wanted to say a big thank you for everything you do here Randy. It's really cool that we have you here to answer all of our reef chemistry related questions. Thank you

Thanks.

I'd just watch for the usual things like closed corals, but i don't see that happening due to something released from the plastic. Anything that is present in plastic is likely to be an organic compound that is fairly hydrophobic so wouldn't be very likely to come out, but if it did, would readily bind to GAC in most cases.
